LO has almost outgrown her 9 month sleepers and finding 1-piece sleepers for 12 month plus seems to be hard to find in brick & mortar stores around here.

I was going to order some from Carters online, but I wanted to check here first. A couple of the reviews have said that they run crazy small and super snug. I know pjs need to be tight, but I don't want to order a bunch and they not work out.

What has been your experience with their pjs for 12 months +?
